Grimrock

hello all.

I assume I have understood the concept of intro.lua but I still have a problem:

[string "CinematicMode.lua"]:0: Not a valid DDS file: mod_assets/textures/cinematic/page01.dds
stack traceback:

my music is played, but game exit, and this error message appears.

I put my picture into mod_asset/textures/cinematic

it's a dds file made with photoshop...

Seems to me you've either saved the .dds improperly....needs to be A8R8G8B8 format and also has to have mipmaps, easy to miss that checkbox ( I use CS5 with Nvidia dds support plugin)

or...

Where you've saved the image leave it as a .dds file, but in your script use the .tga extension ie ( /mypic.tga).

hmmm.

you were right. my export parameters were not the good ones thanks!

now, I can work on intro. yeah!

Glad I could help. Good luck with your intro

Do you (or does anyone) know how to get this to work using the DDS plugin for GIMP? When I get to the dds save dialogue the format A8R8G8B8 is not listed although there are a dozen other variants on the letters RGBA and the number 8! I've tried a few and the game always crashes out at the intro. I definitely ticked mipmaps.. but am not using compression (should I? I thought I read it was not necessary for 2D images)

update.. ok fixed it. I read in another thread I needed to add an alpha channel. then I saved in "RGBA8" format using the GIMP plugin and it seems to work

can you clarify that whole process in one brief tutorial? I'm having a bit of trouble with it

Briefly.. using GIMP.. this is what I did.

* Install the DDS plugin for GIMP if you haven't already (I got it from here - http://code.google.com/p/gimp-dds/)
* open a suitable background image in GIMP (to test, I used a jpg I found online... which due to copyright will not be appropriate for a published mod).
* add an alpha channel to the image. This is done via "Layer > Transparency > Add Alpha Channel" In GIMP 2.6.3
* choose Save As and name the file with a .dds extension
* On the DDS dialogue tick "create mipmaps" and change the Format to RGBA8

This saves your background image as a DDS file, but in your intro.lua script you must refer to it as a .TGA file of the same name.

Hopefully that helps. (and actually works as I've only done it once so far.)

thanks, I'll try it out soon!

great, it worked for me!
I'm using a newer GIMP, version 2.8.2, and I have to "Export" instead of "Save As" in order to be able to choose a DDS option.
I first selected the format RGBA8, then I selected "Generate mipmaps", then back at the top I selected a Compression, since petri mentioned " Use DXT1 for textures without alpha (transparency channel), DXT5 for textures with alpha." I selected "BC3 / DXT5" and it saved a file that was 4MB instead of 16MB when it was uncompressed

Looks like I need to update my GIMP

Thanks for the tips about compression.. my 75Kb jpg became a 3Mb dds file, so I will definitely look at compressing it.
